Well...when I get the chance, ( Not very often, I'm afraid as I'm generally in work on Monday afternoons. ) I go the chess club at the local Mind centre, and play a game of chess or two. I find this is a really good way to relax and calm down and distract myself from any depressed, anxious or negative feelings that I may have.
I can play chess, but if I'm going to have any chance of winning I do need to be " mindful " of what's happening in the game, focus on my moves and those of the other player. And, getting " into the zone " as it were, being " mindful " of what's happening in a game of chess, really helps me to " centre " myself and relax. And, if I win, or even if I just play a good game against a better player, I feel better about myself and my strengths and positive qualities.
Another thing I do to " take a moment " is to watch a film or an episode of a TV series that I like, and can get absorbed in the story of.
For example, each Saturday evening I'm watching a new episode of Doctor Who. And, watching the Doctor, Amy and Rory in a new adventure, I can get so absorbed in the story and what is going to happen next, that it sometimes doesn't feel like 45 minutes at all!
Or, I re-read a favourite book or comic. Re-reading a favourite comic, for example Astro City by Kurt Busiek, is a good way for me to take a moment to breath and relax. The stories are very much about the characters that live in Astro City, and getting absorbed in an issue, or a story across a few issues, always makes me feel better about the world, and myself. Perhaps telling stories, or listening to stories being told, is a particularly " human " thing to do, and so perhaps is a good way to feel connected to other human beings?
( At the moment I'm re-reading a science fiction book, Santiago: A Myth of the Far Future by Mike Resnick. I identify quite a bit with one of the central characters, a character called Sebastian Nightingale Cain, a rather solitary man who is looking for meaning in his life...Although I'm NOT a galactic bounty hunter, of course!
